Improvement in roof-brackets



UNITED STATES DAVID FISHER, 0F MANSFIELD, MASSACHUSETTS.

IMPROVEMENT IN ROOF-BRACKETS.

Specification forming part of Letters Patent No. 118,001, dated August 15, 1871.

To all whom it may concern:

Be it known that I, DAVID FISHER, of Mansiield, in the county of Bristol and State of Massachusetts, have invented a Roof-Bracket to be used in slating, shingling, 85e., of which the following is a full, clear, and exact description, reference being had to the accompanying drawing making part of this specification, in which- Figure 1 is a perspective view of one side of a roof with my improved bracket secured thereto. Fig. 2 is a longitudinal central section through the same.

My invention consists in a strip or bracket of' wood or other suitable material, one end of which is provided with a staple and the opposite end with one or more hooks to be driven into the covering of a roof to form a support for a temporary platform or staging for carpenters, slaters, or masons when shingling, slating, building chimneys, repairing, &c.,the said bracket being' of more simple construction, of easier application, andv more safe than the means heretofore employed for this purpose.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawing A represents a strip of wood ofthe form shown, through one end of which passes the bridge portion a of a staple, B, having its ends pointed. The hole in the strip through which the staple passes is of a diameter slightly larger than that of the bridge portion a in order that it may play loosely therein and allow the staple to be inclined to various angles to conform to roofs of various pitches. b b are small metal plates secured to the sides of the strip where the staple passes through, and are intended to serve as bearings therefor, to prevent the Wood being worn away by frequent use. The end of the strip opposite to that containing the staple is tapered in on each side from c to d, from which latter point to e it is rounded off. (See Fig. 1.) G C are sharp-pointed metallic hooks, pivoted at h to the tapered sides c d, the end fi of each hook opposite to its point l extending as far as d, and being free to swing up and down as required, the whole forming a strong and reliable roof-bracket.

When my improved brackets are to be used upon a roof, D, the strip A is inclined so as to pitch slightly inward thereto, when the staple isl swung into a position which will enable its points to be driven or pressed into one of the boards m covering the roof, when the hooks C C are canted down and also driven in. Two brackets being thus secured .to the roof, a plank is next placed so as to extend over and between them, by which means a platform is provided for supporting the Workman, together with the tools and materials he is required to use. hen the Work on the roof is iinished the brackets may be readily removed by iirst depressing or forcing' down the ends t, simultaneously with which the points l are withdrawmand the staple is then free to be dra-wn out.

From the foregoing description it will be seen that a bracket constructed in accordance with my invention is cheap, simple, compact, and easily applied, and is always safe and reliable, the addition of weight thereon only serving to force the points of the staple and hooks still further into the roof. One hook only may be employed without departing from the spirit of my invention, but I prefer two, as shown.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

The within-described roof-bracket, consisting essentially of the strip A, staple B, and one or more hooks, G, for the purpose set forth.

Witness my hand this 3d day of July, A. D.
